I'm not sure if there's a limit but I've had quite a few out. When you put a sidekick to work, they continue to do so as long as there are open plots. Having some with watering cans and some planting will keep crops growing continuously and quickly. All you have to do is remove weeds and pick crop.Alright, cool.
I just have the one sidekick, but I've unlocked others. I thought you could just have one at a time.
